SRVAL and INIT values may not be properly set for the 9K Block RAM parity bits.

Description:
The parity bits SRVAL and INIT values are not being set properly for Spartan-6 FPGA 9k Block RAM when the DATA_WIDTH = 9.

Affected components:
RAMB8BWER when the DATA_WIDTH is set to 9

Software Behavior:

Behavior in ISE Design Suite 11.5 and earlier: The parity bit in 9-bit mode may have incorrect SRVAL and/or INIT programmed.
Behavior in ISE Design Suite 12.1 and later: This will be fixed in this version of software. SRVAL and INIT values will be properly set.

Workaround:

There is no workaround at this time.
